CVE-2026-73501

A flaw was found in kin-openapi. This vulnerability allows a remote attacker to bypass authentication checks. Specifically, the system incorrectly handles missing authentication configurations, substituting them with a function that does not verify user credentials. This enables unauthorized access to protected resources that should require proper authentication, compromising the application's security.

CVE-2026-75899

A flaw was found in fast-uri, a URI parser for Node.js. The component incorrectly decodes percent escapes in a hostname twice during URI parsing and authority recomposition. This double decoding can allow a remote attacker to manipulate a URI to point to a different network destination, such as a loopback address. This vulnerability can lead to Server-Side Request Forgery (SSRF) and bypass host-based security policies.

Threats

Impact Important

CVE-2026-75931

A flaw was found in fast-uri, a URI parser for Node.js. This vulnerability arises because the parser fails to consistently convert internationalized domain names (IDN) to their standard ASCII form when processing scheme-relative references. This inconsistency can lead to host confusion, where an application might validate a URI against a security policy using one hostname, but then resolve to a different, potentially malicious, hostname. This discrepancy could allow an attacker to bypass security policies and access unauthorized resources.

7.5 (High)

Impact Important

CVE-2026-75975

A flaw was found in fast-uri, a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not fully validate the IPv6 grammar, allowing invalid trailing text in an authority to be silently discarded. This can lead to a malformed, attacker-controlled host being normalized into a different, valid IPv6 destination, such as a local or private IPv6 target. An application normalizing untrusted URLs before outbound requests, redirects, or proxy routing could be redirected, resulting in a server-side request forgery (SSRF) and address-policy bypass.

7.5 (High)

Impact Important

CVE-2026-76172

A flaw was found in fast-uri, a software component used for parsing Uniform Resource Identifiers (URIs) in Node.js applications. This vulnerability arises from an issue in how fast-uri processes the scheme part of a URI, specifically when it contains special characters that are percent-encoded. An attacker can exploit this by crafting a malicious URI, causing the parser to misinterpret the host, which can lead to serious security risks. These risks include unauthorized redirection to external websites, server-side request forgery (SSRF) where the application makes unintended requests to internal or external resources, and bypassing security policies.

7.5 (High)

CVE-2026-73501 (GCVE-0-2026-73501)

Vulnerability from cvelistv5 – Published: 2026-08-12 21:23 – Updated: 2026-08-13 13:06

Title

kin-openapi: ValidationHandler.Load() Fail-Open Authentication Bypass via NoopAuthenticationFunc Default

Summary

kin-openapi is a Go project for handling OpenAPI files. Prior to 0.144.0, ValidationHandler.Load() in openapi3filter/validation_handler.go silently replaces a nil AuthenticationFunc with NoopAuthenticationFunc, which returns nil without checking credentials. This substitution causes every OpenAPI security requirement to be satisfied for unauthenticated requests when an application relies on ValidationHandler as its enforcement middleware. The no-op callback prevents the fail-closed ErrAuthenticationServiceMissing path from being reached and forwards the request to protected handlers that may require an API key, OAuth token, or another security scheme. This issue is fixed in version 0.144.0.

Severity

9.1 (Critical)

CVE-2026-75899 (GCVE-0-2026-75899)

Vulnerability from cvelistv5 – Published: 2026-08-24 09:40 – Updated: 2026-08-24 16:19

Title

fast-uri vulnerable to server-side request forgery via repeated hostname percent-decoding

Summary

fast-uri is a URI parser for Node.js. It decodes percent escapes in a hostname during parsing and then decodes the parsed hostname a second time during authority recomposition, so a single call to normalize or resolve can turn nested percent-encoded input into a different network destination such as a loopback hostname or address. For example, a doubly encoded host that spells out a loopback name decodes to that live host in one operation, which contradicts RFC 3986 section 2.4 that an implementation must not decode the same string more than once. An application that normalizes or resolves an untrusted HTTP-family URI before outbound routing, redirect validation, or a host-policy check can receive a destination different from the one the original encoded host represented, giving a server-side request forgery and host-policy bypass primitive. This is an incomplete-fix variant of CVE-2026-6322. The affected versions are 2.4.1 up to but not including 2.4.5, 3.1.2 up to but not including 3.1.6, and 4.0.0 up to but not including 4.1.3. The issue is fixed in 2.4.5, 3.1.6, and 4.1.3, which normalize percent escapes once and preserve encoded percent signs. Users should upgrade to a patched version.

CVE-2026-75931 (GCVE-0-2026-75931)

Vulnerability from cvelistv5 – Published: 2026-08-24 09:30 – Updated: 2026-08-24 16:28

Title

fast-uri vulnerable to host confusion via skipped IDN canonicalization on scheme-relative references

Summary

fast-uri is a URI parser for Node.js. It canonicalizes a host to its ASCII form only when the input carries an explicit scheme, so a scheme-relative reference such as a host preceded by two slashes is returned with its host verbatim and no error set. As a result fast-uri's own entry points disagree with each other: parse, resolve, normalize, and equal can yield different hosts for the same input depending only on whether a scheme is written out, and equal can return opposite verdicts for the same pair of hosts. An application that extracts a host with fast-uri to check it against a policy list and then resolves the same reference can make its decision on one host while the destination is another, enabling host confusion and policy bypass. The affected versions are 2.4.2 up to but not including 2.4.5, 3.1.3 up to but not including 3.1.6, and 4.0.1 up to but not including 4.1.3. The issue is fixed in 2.4.5, 3.1.6, and 4.1.3, which canonicalize the host consistently across the resolve path. Users should upgrade to a patched version.

CVE-2026-75975 (GCVE-0-2026-75975)

Vulnerability from cvelistv5 – Published: 2026-08-24 09:58 – Updated: 2026-08-24 14:30

Title

fast-uri vulnerable to server-side request forgery via malformed IPv6 normalization

Summary

fast-uri is a URI parser for Node.js. Its custom parser for bracketed IPv6 literals does not validate the complete IPv6 grammar, so invalid trailing text in an authority can be silently discarded and a malformed attacker-controlled host is turned into a different valid IPv6 destination. For example, a bracketed literal with invalid trailing characters is normalized to the unspecified address, which a Node HTTP client then connects to a local service over loopback, and other malformed literals collapse to private-range addresses. No error is set on the parsed result, so an application checking the error field cannot detect the rewrite. An application that normalizes untrusted URLs before outbound requests, redirects, proxy routing, or address-policy enforcement can be redirected to a local or private IPv6 target, giving a server-side request forgery and address-policy bypass primitive. The affected versions are 2.3.1 up to but not including 2.4.5, 3.0.0 up to but not including 3.1.6, and 4.0.0 up to but not including 4.1.3. The issue is fixed in 2.4.5, 3.1.6, and 4.1.3, which validate bracketed IP literals against the full grammar and mark malformed literals as authority errors. Users should upgrade to a patched version.

CVE-2026-76172 (GCVE-0-2026-76172)

Vulnerability from cvelistv5 – Published: 2026-08-24 10:07 – Updated: 2026-08-24 14:29

Title

fast-uri vulnerable to host confusion via percent-encoded scheme normalization

Summary

fast-uri is a URI parser for Node.js. During parsing it runs a legacy decoding pass over the scheme component and never re-escapes the result, and serialization writes the scheme back out verbatim, unlike the host component which is re-escaped. As a result an input whose scheme carries percent-encoded slashes parses as a scheme with no authority, so the parsed host and error are both undefined, yet resolving or normalizing that same input emits a network-path reference whose authority is attacker-chosen and re-parses to that host. An application that allowlists on the parsed host, or treats a reference with no authority as safe to resolve against its base, gets the opposite of what it checked, giving an off-site redirect, server-side request forgery, or address-policy bypass. The legacy decoder also expands non-standard escape forms, widening the issue past upstream filters, and control characters in the scheme can reach the output as raw carriage return and line feed. The affected versions are 2.3.1 up to but not including 2.4.5, 3.0.0 up to but not including 3.1.6, and 4.0.0 up to but not including 4.1.3. The issue is fixed in 2.4.5, 3.1.6, and 4.1.3, which reject a scheme that is not valid after decoding. Users should upgrade to a patched version.

As a result an input whose scheme carries percent-encoded slashes parses as a scheme with no authority, so the parsed host and error are both undefined, yet resolving or normalizing that same input emits a network-path reference whose authority is attacker-chosen and re-parses to that host. An application that allowlists on the parsed host, or treats a reference with no authority as safe to resolve against its base, gets the opposite of what it checked, giving an off-site redirect, server-side request forgery, or address-policy bypass. The legacy decoder also expands non-standard escape forms, widening the issue past upstream filters, and control characters in the scheme can reach the output as raw carriage return and line feed. The affected versions are 2.3.1 up to but not including 2.4.5, 3.0.0 up to but not including 3.1.6, and 4.0.0 up to but not including 4.1.3. The issue is fixed in 2.4.5, 3.1.6, and 4.1.3, which reject a scheme that is not valid after decoding. Users should upgrade to a patched version."
